Polaroid CPL 72mm

Polaroid CPL 72mm

The Polaroid polarising filter reduces glare, ghosting, and unwanted reflections. It filters glare reflected by glossy non-metallic objects, such as glass. It greatly increases the saturation of the sky and leaves, but also clears the haze in landscape shots. Unlike the linear polariser, the circular polarisation filter supports full autofocus and exposure. The filter is made of optical glass and has an aluminium filter ring for higher rigidity and expansion resistance at temperature changes.
